Why COE Prices Change Over Long Periods
A guide to separating recorded COE price changes from explanations involving supply, renewal, EV adoption and household demand.
A comparison between a $30,000 exercise and a later $120,000 exercise shows a fourfold nominal difference. It does not by itself explain the change, establish a steady trend or describe what an owner earned. Choose dated observations before building a long-term explanation.
Start with the price series
Use a consistent category and show the intervening years, including falls. The Category A record of $92,100 belongs to the first January 2013 exercise. It first exceeded $100,000 in the second April 2023 exercise, at $103,721. A narrative that moves that crossing to October changes the chronology.
Read the results archive alongside the trend chart. Keep nominal and inflation-adjusted comparisons separate; a real-price claim needs a named inflation series and base period.
Supply is constrained but not fixed forever
Published quota depends on replacement calculations, the applicable growth component and adjustments. The zero growth rates do not eliminate redistribution or additional injections. LTA’s October 2024 announcement provided for up to about 20,000 additional COEs, progressively from February 2025.
New registrations ten years ago are not a direct forecast of today’s deregistrations. Some vehicles have already left the register, while others may renew. A useful forecast needs the surviving fleet’s age profile and explicit assumptions about those choices.
PQP follows earlier premiums
PQP is used for renewal and averages earlier eligible months. It can be above or below a current auction premium. It creates neither a legal auction floor nor a guarantee that renewal is cheaper than replacement. Compare the applicable month, vehicle condition and full ownership costs.
EV adoption changes the mix of choices
An EV purchase can replace a planned petrol purchase or represent a different transport decision. Registration totals alone do not separate these cases. Powertrain adoption therefore cannot be treated as automatically additive demand for every COE category.
Verify the exact approved variant when comparing categories. A change in eligibility can move potential buyers between pools, while allocation changes can move supply too. Neither direction produces a fixed premium result without knowing the bids.
History does not establish a permanent floor
Demographics, financing and economic conditions are relevant hypotheses, but claims about migrant buyers or dual-income households need direct evidence. A quota chart does not identify those people. Likewise, the April–June 2020 suspension should not be turned into a claim that certificates vanished permanently.
For a practical decision, test a complete package at a lower, unchanged and higher premium assumption. Include the cost of waiting and a walk-away limit. This produces a usable plan even when the direction of the market is uncertain.
